HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 437, 207, 40 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 437, 207, 40 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 437, 207, 40 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 437, 207, 40 is 1.

HCF(437, 207, 40) = 1

Highest Common Factor of 437,207,40 using Euclid's algorithm

Highest Common Factor of 437,207,40 is 1

Step 1: Since 437 > 207, we apply the division lemma to 437 and 207, to get

437 = 207 x 2 + 23

Step 2: Since the reminder 207 ≠ 0, we apply division lemma to 23 and 207, to get

207 = 23 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 23, the HCF of 437 and 207 is 23

Notice that 23 = HCF(207,23) = HCF(437,207) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 40 > 23, we apply the division lemma to 40 and 23, to get

40 = 23 x 1 + 17

Step 2: Since the reminder 23 ≠ 0, we apply division lemma to 17 and 23, to get

23 = 17 x 1 + 6

Step 3: We consider the new divisor 17 and the new remainder 6, and apply the division lemma to get

17 = 6 x 2 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 23 and 40 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(23,17) = HCF(40,23) .
